Subsea arrangement

A subsea arrangement (1) comprising: a base structure (4); a tubular member (2) rotatably mounted to the base structure through an annular bearing (5), wherein a section of the envelop surface of thetubular member is covered by a layer (9) of thermally insulating material; a ring-shaped insulating member (12) of open cell polymer foam mounted to the tubular member, wherein an inner edge (13) of the insulating member is in contact with the envelop surface of the tubular member and the insulating member protrudes radially from the tubular member. The insulating member is positioned between an inner edge (10) of the layer (9) and the annular bearing with a first lateral surface (14) of the insulating member in sliding contact with the inner edge of the layer and with an opposite second lateral surface (15) of the insulating member in contact with a part of the annular bearing. 种海底布置(1)，包括：基部结构(4)；经由环形轴承(5)可旋转地安装到基部结构上的管状构件(2)，其中管状构件的包络表面的段由绝热材料层(9)覆盖；安装到管状构件的开孔聚合物泡沫的环形绝缘构件(12)，其中绝缘构件的内缘(13)与管状构件的包络表面接触，且绝缘构件从管状构
